<p>The present invention relates to a functional digital buckle comprising: a light-emitting unit; an picture imaging treatment unit for imaging a picture of the bottom of a belt passing through a buckle when the belt is coupled with the buckle, wherein the buckle is produced by being reflected by light irradiated from the light-emitting unit; a control unit for detecting x and y coordinate values in both ends of the picture of the bottom of the band passing through the buckle by converting the same, calculating a length value of the same using detected x and y coordinate values, and calculating and displaying an actual waist size by reduce the calculated length value of the same from a pre-saved total belt length value; and a displaying unit for displaying the calculated actual waist size under the control of the control unit. Commercial limits such as the miniaturizing and preciseness realization of a diet digital belt can be relieved. The function of a pedometer is added, and values are shown on a digital crystal liquid, so that the usage of the digital buckle is extended and user convenience is improved. Moreover, clock, time reserving, alarming functions enable a user to conveniently recognize an appointment time beforehand through vibration before others come to know.</p> |
